Refrigeration for Cafes and Restaurants
A cafe or restaurant runs on a handful of fridges that are opened hundreds of times a day, loaded warm and expected to hold temperature beside a cooking line. When one of them drifts, service slows and stock is at risk within the hour.
Commercial focus
Equipment / load / timing
JNF Refrigeration works with cafes and restaurants across the Northern Beaches on the equipment closest to service: preparation counters, under-bench fridges and freezers, display cabinets, upright storage and the cool room behind it all. Most calls are about a unit that is running but not holding temperature, and most of those trace back to airflow, door use or a condenser that has quietly clogged with grease.
Equipment we look after
Why cafe refrigeration fails the way it does
Kitchen refrigeration works in the worst conditions in the building. A prep counter beside a grill is rejecting heat into air that may be sitting at 35°C, through a condenser that is collecting a film of grease and dust every hour it runs. Its door is opened every few minutes, stock goes in warm from deliveries, and it often has centimetres of clearance where the manufacturer asked for far more.
None of that breaks a unit outright. What it does is take away the margin, so a fridge that coped in June cannot recover between door openings in January. That is why so many cafe faults appear gradually, look like a controller problem and turn out to be airflow. Cleaning the condenser and restoring clearance often recovers more than people expect; when it does not, the fault is inside the system and needs licensed work.
Keeping service running when a unit drifts
If a fridge is warm during service, the order of operations matters. Keep the door shut, check that the unit has power and that nothing is stacked against the internal fan, and put a probe thermometer in the product rather than trusting the display. Potentially hazardous food that has been above 5°C needs to be handled according to your food safety plan, and the 2-hour/4-hour guidance is the usual reference point.
Then call with the make and model, what the thermometer says, when the drift started and whether anything changed. A fault that has been coming on for a week is a different conversation to one that appeared after a delivery blocked the return air, and knowing which usually decides what comes on the van.
Planned servicing that fits a cafe's day
Servicing intervals for cafe equipment are shorter than most operators expect. Refrigeration sharing air with a cooking line is usually worth a look every three months; display and storage equipment away from the heat can often stretch to six. The right interval is the one where the technician keeps finding the equipment in reasonable condition.
The best time to have it done is the one that costs you least: before opening, after close, or on the quiet weekday you already know about. Beachfront cafes should add a pre-summer check on external condensers, since salt corrosion on the Northern Beaches shortens coil life and a marginal unit will fail in the first sustained hot spell.
Frequently asked questions
Do you repair prep counters and under-bench fridges in cafes?
Yes. Preparation counters, sandwich bars, under-bench fridges and freezers, display cabinets, uprights and cool rooms are the core of JNF Refrigeration's cafe and restaurant work across the Northern Beaches.
Our display fridge is cold at the back but warm at the front. Why?
On a glass-door cabinet that pattern usually means warm air is getting in: frequent openings, a seal that has stopped sealing, or stock loaded warm and packed against the front. On an open-front cabinet the air curtain that holds the cold in is easily disturbed by a nearby fan, an air-conditioning vent or a door, and the front shelf pays for it. Check the seal and the surroundings first; if both are fine, the airflow inside the cabinet needs looking at.
Can servicing be done before we open or after we close?
Timing depends on the job and availability, but early and late windows are a normal part of cafe work and worth raising when you enquire so the practical options can be discussed rather than assumed.
How long does stock stay safe if a fridge fails during service?
Not long in a small unit. A prep counter or under-bench fridge has very little thermal mass and can leave the safe range inside an hour in a hot kitchen; a closed cool room holds far longer. Put a thermometer in the product, note the time, and follow your food safety plan for anything that has been above 5°C.
